ABSTRACT:
A cab extender assembly (200) for selectively manipulating an aerodynamic drag of a vehicle (100) is provided. The cab extender assembly includes a dynamic cab extender (206a) and a control system (208) coupled to the dynamic cab extender. The control system is adapted to selectively position the dynamic cab extender between a stowed position, a deployed position in which the dynamic cab extender is substantially aligned with a side of the vehicle, and a braking position in which the dynamic cab extender is at least partially disposed into an airstream passing along the side of the vehicle to increase a drag coefficient of the vehicle. The cab extender assembly may also include a fixed cab extender (204a) substantially aligned with the dynamic cab extender when the dynamic cab extender is in the deployed position. A method of operating a cab extender assembly is also disclosed.
